I'm sorry, Luis - but I don't think this is that good. It is "entitled" sister and you say it is a shot of your sister...but the main figure in the shot is blurred, we don't see much of her and her expression is hard to fathom. The blur may have worked if we, the viewer, were following her gaze out of the window - in effect, seeing what she was seeing. However, with this composition, i don't think it works, sorry.
